thorpej 1e2aeb4a35 Add a comment documenting the last change. 1998-09-18 19:28:22 +00:00
thorpej 5dd4b45577 Don't use the nointr pool page allocator for the uao_swhash_elt pool. We 
need to ensure that these come from a non-pageable kernel map, otherwise
we can run into a deadlock condition (as noticed by Chuck Silvers).

thorpej 5a4981d9b8 Use the pool allocator w/ the "nointr" pool page allocator for uvm_aobj 
and uao_swhash_elt structures.  Also, fix a bug in uao_set_swlot() where
if setting the swslot to 0 (freeing swap resources), and no swslot was
currently allocated, a new entry would be allocated anyhow (revealed during
pool'ification).

drochner 9b25897ec0 minor consistency nit: the page index into an anon object is always 
assigned to from integer types, and it is compared to integers. So
let it be an integer instead of vsize_t.

chs 249efd73a1 enable hashtables for swapslot storage - deadlock is fixed. 
fix initialization of swhash entries.

mrg f2caacc717 initial import of the new virtual memory system, UVM, into -current. 
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the UVM kernel code portion.


this will be KNF'd shortly.  :-)
